The World of Spirits, called by some The Other World, is a secret plane of existence located at the heart of the world tree Yggdrasil.
This sacred tree, which the Elves have venerated for millennia, is none other than the very incarnation of the King of Spirits, Taurus.
At the center of this tree lies the Fountain of Youth, whose water is renowned for granting immortality to all the spirits that live there.
Taurus fathered seven daughters over the ages. They are called the Seven Pleiades. Each of them is the matriarch and guardian of a spiritual race and is tied to a specific element from which she draws her power.
